How to Setup Frsky FPort

FPort is the latest RC serial protocol that brings a few improvements over the existing RX and telemetry protocols. This tutorial will explain the advantages of FPort, and how to set it up on Betaflight flight controllers for your mini quad.

FPort is an “RX protocol” – a communication interface between receiver and other components, such as a sensor, or flight controller.

FPort (possibly stands for “Frsky Port”?), is developed by both Betaflight Dev Team and Frsky, it’s great to see big players working together to make the hobby better.

FPort combines SBUS and Smarport Telemetry into 1 single wire

cutting down cable management and soldering

save you a UART port because SBUS and Smartport take up 2 separate UART’s

FPort is an uninverted protocol, so hopefully we don’t have to worry about doing “uninversion hacks” on F4 FC (in future Frsky receivers)

There are some other technical benefits, but the two reasons above are enough to explain my excitement .

It’s exciting to see the awesome improvements of FPort, but it can be better! Some other competitors of Frsky offer solutions that already have these benefits, but more importantly they have lower latency and higher refresh rates than SBUS, which can largely improve the handling of your quad, such as TBS’s Crossfire we recently tested.
